 ところで、失禁用の着用物品では、尿速が遅いケース及び尿量が多いケースの双方が想定される。尿速が遅いケースでは、着用者の肌を伝わって着用物品の外部に漏れ出す可能性がある。従って、着用者の***口(***域)と吸収体との密着性が高いことが重要である。一方で、尿量が多いケースでは、吸収体によって尿を一時に吸収することができず、着用物品の外部に漏れ出す可能性がある。 By the way, in the case of wearing articles for incontinence, both cases where the urine speed is slow and cases where the urine volume is large are assumed. In a case where the urine speed is slow, there is a possibility of leaking out of the wearing article through the wearer's skin. Therefore, it is important that the adhesion between the wearer's excretion opening (excretion area) and the absorber is high. On the other hand, in a case where the amount of urine is large, urine cannot be absorbed at a time by the absorber, and there is a possibility of leaking out of the worn article.

[実施形態の概要]
 第1に、実施形態に係る着用物品は、胴回り領域及び股下領域を有するシャーシと、少なくとも股下領域に設けられた吸収体を有する吸収体本体とを備える。着用物品は、股下領域において吸収体に重なっており、かつ、着用物品の幅方向の略中央において着用物品の長手方向に沿って延びるように配置された第1弾性部材と、着用物品の幅方向における胴回り領域の両側端から股下領域内に湾曲して、着用物品の幅方向に沿って吸収体を横断する伸縮応力線の少なくとも一部を構成する第2弾性部材とを備える。伸縮応力線のうち、吸収体を横断する部分の伸縮応力は、第1弾性部材の伸縮応力よりも小さい。
[Outline of Embodiment]
First, the wearing article according to the embodiment includes a chassis having a waist region and a crotch region, and an absorbent body having an absorber provided at least in the crotch region. The wearing article is overlapped with the absorber in the crotch region, and is arranged so as to extend along the longitudinal direction of the wearing article at a substantially center in the width direction of the wearing article, and the width direction of the wearing article And a second elastic member that is curved into the crotch region from both side ends of the waistline region and constitutes at least a part of a stretching stress line that crosses the absorbent body along the width direction of the wearing article. Of the stretching stress line, the stretching stress of the portion crossing the absorber is smaller than the stretching stress of the first elastic member.
 なお、第1弾性部材と伸縮応力線は、互いにほぼ直交するように延びていることが好ましい。第2弾性部材は、以下のように、伸縮応力線の少なくとも一部を形成することができる。いくつかの実施形態においては、第2弾性部材は、伸縮応力線の全てに沿っており、着用物品の幅方向に吸収体を横断している。従って、第2弾性部材は、伸縮応力線の全てを形成している。しかし、他の実施形態においては、第2弾性部材は吸収体を横断する部分において不連続であり、この場合、第2弾性部材には吸収体を横断する部分がない、または、吸収体を横断する部分の第2弾性部材が断続的である。第2弾性部材が吸収体を横断しない場合であっても、伸縮応力線は存在する。この場合、伸縮応力線は、第2弾性部材の、吸収体のいずれかの側面における部分からなる効果により形成される。さらに、実施形態には、吸収体の側面部分に第2弾性部材が部分的に存在するが、吸収体の幅全体を完全にまたは断続的にも横断しない場合も含まれる。 In addition, it is preferable that the 1st elastic member and the expansion-contraction stress line are extended so that it may mutually orthogonally cross. The second elastic member can form at least a part of the stretch stress line as follows. In some embodiments, the second elastic member extends along all of the stretching stress lines and crosses the absorbent body in the width direction of the wearing article. Therefore, the 2nd elastic member forms all the expansion-contraction stress lines. However, in other embodiments, the second elastic member is discontinuous in the portion that crosses the absorber, in which case the second elastic member does not have a portion that crosses the absorber or crosses the absorber. The second elastic member of the part to perform is intermittent. Even when the second elastic member does not cross the absorber, the stretch stress line exists. In this case, the expansion / contraction stress line is formed by the effect of the portion of the second elastic member on either side of the absorber. Further, the embodiment includes a case where the second elastic member is partially present on the side surface portion of the absorbent body but does not completely or intermittently traverse the entire width of the absorbent body.
 第1弾性部材と第2弾性部材は、同一でもあってもよく、異なるものであってもよい。ある実施形態においては、第1弾性部材と第2弾性部材はそれぞれ、互いに平行だが違う方向に向かって延びる複数本の糸状弾性部材を備えている。しかし、本発明は、糸状弾性部材の存在に限定されるものではない。第1弾性部材及び第2弾性部材は、例えば、帯状の弾性シートであってもよい。 The first elastic member and the second elastic member may be the same or different. In an embodiment, each of the first elastic member and the second elastic member includes a plurality of thread-like elastic members that are parallel to each other but extend in different directions. However, the present invention is not limited to the presence of the thread-like elastic member. The first elastic member and the second elastic member may be, for example, a belt-like elastic sheet.
 第1弾性部材は3本から8本の糸状弾性部材を備え、第2弾性部材は1本から4本の糸状弾性部材を備えることが好ましい。吸収体を横断する部分の弾性応力が第1弾性部材の弾性応力より小さくなるよう、第1弾性部材は第2弾性部材よりも少ない糸状弾性部材を備えていてもよい。 The first elastic member preferably includes 3 to 8 thread-like elastic members, and the second elastic member preferably includes 1 to 4 thread-like elastic members. The first elastic member may be provided with fewer thread-like elastic members than the second elastic member so that the elastic stress of the portion crossing the absorber is smaller than the elastic stress of the first elastic member.
 第1弾性部材は全ての側面において吸収体に囲まれるよう、吸収体より小さな寸法であることが好ましい。第1弾性部材は、着用物品の幅方向においてほぼ中央に配置される。 It is preferable that the first elastic member has a size smaller than that of the absorber so as to be surrounded by the absorber on all sides. The first elastic member is disposed substantially at the center in the width direction of the wearing article.
 第1の実施形態における第1弾性部材の長さは、吸収体本体の長さの6分の1から3分の1であることが好ましい。第1弾性部材は、吸収体本体の縦方向の中心に重なることが好ましい。いくつかの実施形態においては、第1弾性部材は吸収体本体の縦方向の中央から、吸収体本体の正面または背面に向かって延びている。 The length of the first elastic member in the first embodiment is preferably 1/6 to 1/3 of the length of the absorber body. It is preferable that the first elastic member overlaps the longitudinal center of the absorbent body. In some embodiments, the first elastic member extends from the longitudinal center of the absorbent body toward the front or back of the absorbent body.
 かかる特徴によれば、第1弾性部材は、股下領域において吸収体に重なっており、かつ、着用物品の幅方向の略中央において着用物品の長手方向に沿って延びるように配置される。すなわち、第1弾性部材によって***域と吸収体との密着性が向上する。従って、尿速が遅いケースであっても、着用物品の外部に尿が漏れ出すことを抑制することができる。また、伸縮応力線のうち、吸収体を横断する部分の伸縮応力は、第1弾性部材の伸縮応力よりも小さい。すなわち、吸収体を横断する部分において、伸縮応力が相対的に小さい尿溜まりが形成される。従って、尿量が多いケースであっても、着用物品の外部に尿が漏れ出すことを抑制することができる。なお、尿溜まりとは、尿を一時的に収容するための間隙である。尿溜まりによって、吸収体によって尿を吸収するまでの時間が確保される。 According to such a feature, the first elastic member overlaps the absorbent body in the crotch region, and is disposed so as to extend along the longitudinal direction of the worn article at the approximate center in the width direction of the worn article. That is, the adhesion between the excretion area and the absorber is improved by the first elastic member. Therefore, even in a case where the urine speed is slow, urine can be prevented from leaking out of the worn article. Moreover, the elastic stress of the part which crosses an absorber among elastic stress lines is smaller than the elastic stress of a 1st elastic member. That is, a urine pool having a relatively small expansion / contraction stress is formed in a portion crossing the absorber. Therefore, even in a case where the amount of urine is large, leakage of urine to the outside of the worn article can be suppressed. The urine reservoir is a gap for temporarily storing urine. The time until the urine is absorbed by the absorber is secured by the urine pool.
 第2に、実施形態に係る着用物品は、胴回り領域及び股下領域を有するシャーシと、少なくとも股下領域に設けられた吸収体を有する吸収体本体とを備える。着用物品は、股下領域において吸収体に重なっており、かつ、着用物品の幅方向の略中央において着用物品の長手方向に沿って延びるように配置された第1弾性部材を備える。第1弾性部材は、着用物品の長手方向において着用物品の略中央部分に設けられた股下直下部分と、着用物品の長手方向において股下直下部分に連続する延設部分とを含む。延設部分の伸縮応力は、股下直下部分の伸縮応力よりも小さい。 Secondly, the wearing article according to the embodiment includes a chassis having a waist region and a crotch region, and an absorbent body having an absorber provided at least in the crotch region. The wearing article includes a first elastic member that overlaps the absorbent body in the crotch region and is disposed so as to extend along the longitudinal direction of the wearing article at a substantially center in the width direction of the wearing article. The first elastic member includes a portion immediately below the crotch provided at a substantially central portion of the wearing article in the longitudinal direction of the wearing article, and an extending portion continuous with the portion directly below the crotch in the longitudinal direction of the wearing article. The extension stress of the extended portion is smaller than the extension stress of the portion immediately below the crotch.
 本発明の第2の実施形態は第1の実施形態から独立していてもよく、関連していてもよい。第1弾性部材の該当する二つの部分は、同一であってもよく、異なるものであってもよい。ある実施形態においては、二つの部分はそれぞれ平行に延びる複数の糸状弾性部材を備えている。しかし、本発明は、糸状弾性部材の存在に限定されるものではない。第1弾性部材は、例えば、帯状の弾性シートであってもよい。 The second embodiment of the present invention may be independent of or related to the first embodiment. Two corresponding portions of the first elastic member may be the same or different. In one embodiment, each of the two portions includes a plurality of thread-like elastic members extending in parallel. However, the present invention is not limited to the presence of the thread-like elastic member. The first elastic member may be, for example, a belt-like elastic sheet.
 第1弾性部材の着用者の股下直下部分は、例えば、3本から8本の糸状弾性部材を備え、延設部分は1本から4本の糸状弾性部材を備えることが好ましい。延設部分の弾性応力が股下直下部分の弾性応力より小さくなるよう、延設部分は股下直下部分より少ない糸状弾性部材を備えていてもよい。 It is preferable that the part directly under the crotch of the wearer of the first elastic member is provided with, for example, 3 to 8 thread-like elastic members, and the extended part is provided with 1 to 4 thread-like elastic members. The extended portion may be provided with a thread-like elastic member that is smaller than the portion immediately below the crotch so that the elastic stress of the extended portion is smaller than the elastic stress of the portion immediately below the crotch.
 本第2の実施形態においては、第1弾性部材は延設部分を有し、吸収体本体の幅方向に係る第1弾性部材の上記幅が当てはまる。しかし、着用中における着用者の股下直下部分と延設部分を備える第1弾性部材の長さは、吸収体本体のほぼ3分の1から半分の長さであることが好ましい。第1弾性部材は、吸収体本体の縦方向にほぼ中心に重なることが好ましい。 In the second embodiment, the first elastic member has an extending portion, and the above-described width of the first elastic member in the width direction of the absorbent body is applied. However, it is preferable that the length of the first elastic member including the portion directly below the crotch and the extending portion of the wearer during wearing is approximately one third to half the length of the absorbent body. It is preferable that the first elastic member substantially overlaps the center in the longitudinal direction of the absorbent body.
 一般的には(従って、例示された実施形態に限定されることなく)、第1弾性部材の股下直下部分は、着用物品の長手方向において着用物品の略中央部分に設けられる。すなわち、第1弾性部材の股下直下部分によって***域と吸収体との密着性が向上する。従って、尿速が遅いケースであっても、着用物品の外部に尿が漏れ出すことを抑制することができる。また、第1弾性部材のうち、延設部分の伸縮応力は、股下直下部分の伸縮応力よりも小さい。すなわち、股下直下部分に連続する延設部分において、伸縮応力が相対的に小さい尿溜まりが形成される。従って、尿量が多いケースであっても、着用物品の外部に尿が漏れ出すことを抑制することができる。なお、尿溜まりとは、尿を一時的に収容するための間隙である。尿溜まりによって、吸収体によって尿を吸収するまでの時間が確保される。 Generally (thus, without being limited to the illustrated embodiment), the portion immediately below the crotch of the first elastic member is provided at a substantially central portion of the wearing article in the longitudinal direction of the wearing article. That is, the adhesion between the excretory region and the absorbent body is improved by the portion immediately below the crotch of the first elastic member. Therefore, even in a case where the urine speed is slow, urine can be prevented from leaking out of the worn article. Moreover, the expansion / contraction stress of the extension part among the 1st elastic members is smaller than the expansion / contraction stress of the part directly under the crotch. That is, a urine pool having a relatively small expansion / contraction stress is formed in the extended portion that continues to the portion immediately below the crotch. Therefore, even in a case where the amount of urine is large, leakage of urine to the outside of the worn article can be suppressed. The urine reservoir is a gap for temporarily storing urine. The time until the urine is absorbed by the absorber is secured by the urine pool.

 中央弾性部材被覆シート42Cは、外装トップシート21と吸収体裏面シート35との間に設けられる。上述したように、中央弾性部材被覆シート42Cと吸収体裏面シート35との間には中央弾性部材41Cが配置される。 The central elastic member covering sheet 42 </ b> C is provided between the exterior top sheet 21 and the absorber back sheet 35. As described above, the central elastic member 41C is disposed between the central elastic member covering sheet 42C and the absorber back sheet 35.
 ここで、第1実施形態において、中央弾性部材41Cを構成する複数本の糸状弾性部材の間隔P(図4を参照)は、後レッグ弾性部材24Rのうち、吸収体を横断する部分を構成する複数本の糸状弾性部材の間隔Q(図5を参照)よりも小さい。また、後レッグ弾性部材24Rを構成する1本の糸状弾性部材の伸縮応力は、中央弾性部材41Cを構成する1本の糸状弾性部材の伸縮応力よりも大きいことが好ましい。このようなケースでは、間隔Pが間隔Qよりも小さいため、中央弾性部材41Cによって、***域に対する吸収体の密着性が高い。一方で、間隔Qが間隔Pよりも大きいため、着用者の脚周り部分の肌に対する着用物品1の当たりが弱く、着用物品1が部分的に着用者の脚周り部分の肌に押し当てられないため、着用時の弾性部材による締め付け感をやわらげることができる。 Here, in 1st Embodiment, the space | interval P (refer FIG. 4) of the several thread-like elastic member which comprises the center elastic member 41C comprises the part which crosses an absorber among the back leg elastic members 24R. It is smaller than the interval Q between the plurality of thread-like elastic members (see FIG. 5). Moreover, it is preferable that the stretching stress of one thread-like elastic member constituting the rear leg elastic member 24R is larger than the stretching stress of one thread-like elastic member constituting the central elastic member 41C. In such a case, since the space | interval P is smaller than the space | interval Q, the adhesiveness of the absorber with respect to an excretion area is high by the center elastic member 41C. On the other hand, since the interval Q is larger than the interval P, the wear article 1 is weakly hit against the skin around the wearer's leg, and the wear article 1 is not partially pressed against the skin around the wearer's leg. Therefore, the feeling of tightening by the elastic member at the time of wearing can be eased.
 また、第1実施形態において、後レッグ弾性部材24Rは、中央弾性部材41Cよりも非肌面側に配置される(図5を参照)。すなわち、後レッグ弾性部材24Rは、中央弾性部材41Cよりも吸収体から離れた位置に設けられる。従って、後レッグ弾性部材24Rのうち、吸収体を横断する部分が吸収体の幅(幅方向Wにおける吸収体のサイズ)が縮みにくく、***域と吸収体との密着性の低下が抑制される。一方で、中央弾性部材41Cは、後レッグ弾性部材24Rよりも吸収体に近い位置に設けられる。従って、吸収体が***域に密着するように変形しやすい。 In the first embodiment, the rear leg elastic member 24R is disposed on the non-skin surface side with respect to the central elastic member 41C (see FIG. 5). That is, the rear leg elastic member 24R is provided at a position farther from the absorber than the central elastic member 41C. Therefore, in the rear leg elastic member 24R, the width of the absorber (the size of the absorber in the width direction W) does not shrink at the portion that crosses the absorber, and the decrease in the adhesion between the excretory area and the absorber is suppressed. . On the other hand, the central elastic member 41C is provided at a position closer to the absorber than the rear leg elastic member 24R. Therefore, the absorber is easily deformed so as to be in close contact with the excretion area.
 なお、第1実施形態において、吸収体本体200は、表面シート31、吸収体表面シート32、第1吸収体層33、第2吸収体層34及び吸収体裏面シート35によって構成される。或いは、吸収体本体200は、これらに加えて、防漏弾性部材41A、防漏弾性部材41B、中央弾性部材41C、防漏弾性部材シート42A、防漏弾性部材シート42B及び中央弾性部材被覆シート42Cによって構成される。 In addition, in 1st Embodiment, the absorber main body 200 is comprised by the surface sheet 31, the absorber surface sheet 32, the 1st absorber layer 33, the 2nd absorber layer 34, and the absorber back surface sheet 35. FIG. Alternatively, in addition to these, the absorbent body 200 includes a leak-proof elastic member 41A, a leak-proof elastic member 41B, a central elastic member 41C, a leak-proof elastic member sheet 42A, a leak-proof elastic member sheet 42B, and a central elastic member covering sheet 42C. Consists of.
 (伸縮応力の関係)
 以下において、第1実施形態に係る伸縮応力の関係について、図面を参照しながら説明する。以下においては、図6~図9を参照しながら、パターン1~パターン4について説明する。なお、図6~図9では、長手方向Lにおける着用物品1の全体が示されている。
(Relationship between stretching stress)
Hereinafter, the relationship between the stretching stresses according to the first embodiment will be described with reference to the drawings. Hereinafter, the patterns 1 to 4 will be described with reference to FIGS. 6 to 9, the entire wearing article 1 in the longitudinal direction L is shown.
 図6~図9に示すように、パターン1~パターン4の共通構成として、着用物品1は、以下の構成を有する。具体的には、着用物品1は、後胴回り領域110R及び股下領域120を有する。股下領域120は、股下直下領域120M及び中間領域120Rを有する。 As shown in FIGS. 6 to 9, as a common configuration of the patterns 1 to 4, the wearing article 1 has the following configuration. Specifically, the wearing article 1 has a rear waistline region 110 </ b> R and a crotch region 120. The crotch region 120 includes a crotch immediate region 120M and an intermediate region 120R.
 股下直下領域120Mは、着用者が両脚を閉じたときに両脚間の幅が最も狭くなる着用者の股間(***域)に当接する領域である。中間領域120Rは、股下直下領域120Mと後胴回り領域110Rとの間に介在する領域である。 The region 120M immediately below the crotch is a region that comes into contact with the wearer's crotch (excretion area) where the width between the legs is the narrowest when the wearer closes both legs. The intermediate region 120R is a region interposed between the inseam region 120M and the rear waistline region 110R.
 上述した中央弾性部材41Cは、股下直下領域120Mにおいて長手方向Lに沿って延びるように配置される。但し、中央弾性部材41Cは、中間領域120Rに達していない。 The central elastic member 41C described above is arranged so as to extend along the longitudinal direction L in the region 120M immediately below the crotch. However, the central elastic member 41C does not reach the intermediate region 120R.
 上述した伸縮応力線310は、幅方向Wにおける後胴回り領域110Rの両側端から股下領域120内に湾曲して、吸収体本体200に設けられた吸収体(第1吸収体層33及び第2吸収体層34)を幅方向Wにおいて横断する。 The above-described stretching stress line 310 is curved into the crotch region 120 from both side ends of the rear waistline region 110R in the width direction W, and the absorber (the first absorber layer 33 and the second absorption layer) provided in the absorber main body 200. The body layer 34) is traversed in the width direction W.
 ここで、伸縮応力線310のうち、吸収体を横断する部分の伸縮応力は、パターン1~パターン4に共通して、中央弾性部材41Cの伸縮応力よりも小さい。これによって、中間領域120Rにおいて、伸縮応力線310のうち、吸収体を横断する部分には、伸縮応力が相対的に小さい尿溜まり320が形成される。なお、尿溜まり320は、尿を一時的に収容する間隙である。尿溜まりによって、吸収体によって尿を吸収するまでの時間が確保される。 Here, in the stretching stress line 310, the stretching stress of the portion crossing the absorber is smaller than the stretching stress of the central elastic member 41C in common with the patterns 1 to 4. As a result, in the intermediate region 120R, a urine pool 320 having a relatively small stretching stress is formed in a portion of the stretching stress line 310 that crosses the absorber. The urine pool 320 is a gap for temporarily storing urine. The time until the urine is absorbed by the absorber is secured by the urine pool.
 なお、以下の説明において、中央弾性部材41Cと、後レッグ弾性部材24Rとの応力範囲及び応力比率は、次のような値であることが好ましい。中央弾性部材41Cの応力範囲は、0.05~1.0N/cm、後レッグ弾性部材24R(吸収体横断部分)の応力範囲は、0~0.4N/cm、後レッグ弾性部材24R(吸収体非横断部分)の応力範囲は、0.2~3.0N/cmであることが好ましい。また、後レッグ弾性部材24R(吸収体横断部分)/中央弾性部材41Cの応力比率は、1.0未満、後レッグ弾性部材24R(吸収体横断部分)/後レッグ弾性部材24R(吸収体非横断部分)は、0.9以下、中央弾性部材41C/後レッグ弾性部材24R(吸収体非横断部部分)は、0.9以下であることが好ましい。 In the following description, the stress range and stress ratio between the central elastic member 41C and the rear leg elastic member 24R are preferably the following values. The stress range of the central elastic member 41C is 0.05 to 1.0 N / cm, and the stress range of the rear leg elastic member 24R (absorber crossing portion) is 0 to 0.4 N / cm, and the rear leg elastic member 24R (absorption) The stress range of the non-body-crossing portion is preferably 0.2 to 3.0 N / cm. Further, the stress ratio of the rear leg elastic member 24R (absorber crossing portion) / the central elastic member 41C is less than 1.0, the rear leg elastic member 24R (absorber crossing portion) / the rear leg elastic member 24R (absorber non-crossing). The portion) is preferably 0.9 or less, and the central elastic member 41C / rear leg elastic member 24R (absorber non-crossing portion portion) is preferably 0.9 or less.
 (パターン1)
 以下において、パターン1について、図6を参照しながら説明する。図6に示すように、後レッグ弾性部材24Rは、伸縮応力線310の一部を構成する。後レッグ弾性部材24Rは、伸縮応力線310上において、吸収体を横断する部分で不連続である。すなわち、伸縮応力線310上において、吸収体を横断する部分には、後レッグ弾性部材24Rが設けられていない。これによって、伸縮応力線310のうち、吸収体を横断する部分の伸縮応力は、中央弾性部材41Cの伸縮応力よりも小さくなる。
(Pattern 1)
Hereinafter, the pattern 1 will be described with reference to FIG. As shown in FIG. 6, the rear leg elastic member 24 </ b> R constitutes a part of the stretching stress line 310. The rear leg elastic member 24 </ b> R is discontinuous at the portion crossing the absorber on the stretching stress line 310. That is, the rear leg elastic member 24 </ b> R is not provided in a portion crossing the absorber on the stretch stress line 310. As a result, the stretching stress of the portion of the stretching stress line 310 that crosses the absorber becomes smaller than the stretching stress of the central elastic member 41C.
 なお、パターン1において、後レッグ弾性部材24Rの伸縮応力は、中央弾性部材41Cの伸縮応力よりも大きいことが好ましい。 In the pattern 1, it is preferable that the stretching stress of the rear leg elastic member 24R is larger than the stretching stress of the central elastic member 41C.
 (パターン2)
 以下において、パターン2について、図7を参照しながら説明する。図7に示すように、後レッグ弾性部材24Rは、伸縮応力線310の全体を構成する。
(Pattern 2)
Hereinafter, the pattern 2 will be described with reference to FIG. As shown in FIG. 7, the rear leg elastic member 24 </ b> R constitutes the entire stretch stress line 310.
 後レッグ弾性部材24Rは、横断部分24R1及び非横断部分24R2を有する。横断部分24R1は、伸縮応力線310のうち、吸収体を横断する部分を構成する。非横断部分24R2は、伸縮応力線310のうち、吸収体を横断する部分以外を構成する。 The rear leg elastic member 24R has a transverse portion 24R1 and a non-crossing portion 24R2. The crossing portion 24R1 constitutes a portion of the stretching stress line 310 that crosses the absorber. The non-crossing portion 24R2 constitutes the stretch stress line 310 other than the portion that crosses the absorber.
 パターン2では、横断部分24R1は、断続的に切断されている。例えば、横断部分24R1には、カッターなどによって断続的なミシン目が入っている。すなわち、伸縮応力線310上において、吸収体を横断する部分には、後レッグ弾性部材24Rが点線状に残っている。これによって、横断部分24R1の伸縮応力は、中央弾性部材41Cの伸縮応力よりも小さくなる。 In the pattern 2, the transverse portion 24R1 is cut intermittently. For example, the transverse portion 24R1 is intermittently perforated by a cutter or the like. That is, on the stretch stress line 310, the rear leg elastic member 24R remains in a dotted line shape at a portion crossing the absorber. As a result, the stretching stress of the transverse portion 24R1 becomes smaller than the stretching stress of the central elastic member 41C.
 なお、パターン2において、非横断部分24R2の伸縮応力は、横断部分24R1の伸縮応力よりも大きく、中央弾性部材41Cの伸縮応力よりも大きいことが好ましい。 In the pattern 2, the stretching stress of the non-crossing portion 24R2 is preferably larger than the stretching stress of the transverse portion 24R1 and larger than the stretching stress of the central elastic member 41C.
 (パターン3)
 以下において、パターン3について、図8を参照しながら説明する。図8に示すように、後レッグ弾性部材24Rは、伸縮応力線310の全体を構成する。
(Pattern 3)
Hereinafter, the pattern 3 will be described with reference to FIG. As shown in FIG. 8, the rear leg elastic member 24 </ b> R constitutes the entire stretch stress line 310.
 後レッグ弾性部材24Rは、横断部分24R1及び非横断部分24R2を有する。横断部分24R1は、伸縮応力線310のうち、吸収体を横断する部分を構成する。非横断部分24R2は、伸縮応力線310のうち、吸収体を横断する部分以外を構成する。 The rear leg elastic member 24R has a transverse portion 24R1 and a non-crossing portion 24R2. The crossing portion 24R1 constitutes a portion of the stretching stress line 310 that crosses the absorber. The non-crossing portion 24R2 constitutes the stretch stress line 310 other than the portion that crosses the absorber.
 パターン3では、後レッグ弾性部材24Rは、複数本の糸状弾性部材によって構成される。横断部分24R1を構成する糸状弾性部材の本数は、非横断部分24R2を構成する糸状弾性部材の本数よりも少ない。これによって、横断部分24R1の伸縮応力は、中央弾性部材41Cの伸縮応力よりも小さくなる。 In Pattern 3, the rear leg elastic member 24R is composed of a plurality of thread-like elastic members. The number of thread-like elastic members constituting the transverse part 24R1 is smaller than the number of thread-like elastic members constituting the non-crossing part 24R2. As a result, the stretching stress of the transverse portion 24R1 becomes smaller than the stretching stress of the central elastic member 41C.
 なお、パターン3において、非横断部分24R2の伸縮応力は、横断部分24R1の伸縮応力よりも大きく、中央弾性部材41Cの伸縮応力よりも大きいことが好ましい。 In the pattern 3, the stretching stress of the non-crossing portion 24R2 is preferably larger than the stretching stress of the transverse portion 24R1 and larger than the stretching stress of the central elastic member 41C.
 (パターン4)
 以下において、パターン4について、図9を参照しながら説明する。図9に示すように、後レッグ弾性部材24Rは、伸縮応力線310の全体を構成する。
(Pattern 4)
Hereinafter, the pattern 4 will be described with reference to FIG. As shown in FIG. 9, the rear leg elastic member 24 </ b> R constitutes the entire stretch stress line 310.
 後レッグ弾性部材24Rは、横断部分24R1及び非横断部分24R2を有する。横断部分24R1は、伸縮応力線310のうち、吸収体を横断する部分を構成する。非横断部分24R2は、伸縮応力線310のうち、吸収体を横断する部分以外を構成する。 The rear leg elastic member 24R has a transverse portion 24R1 and a non-crossing portion 24R2. The crossing portion 24R1 constitutes a portion of the stretching stress line 310 that crosses the absorber. The non-crossing portion 24R2 constitutes the stretch stress line 310 other than the portion that crosses the absorber.
 パターン4では、横断部分24R1の伸縮応力は、非横断部分24R2の伸縮応力よりも小さい。 In pattern 4, the stretching stress of the transverse part 24R1 is smaller than the stretching stress of the non-crossing part 24R2.
 例えば、外装トップシート21と後外装バックシート22Rとの間に後レッグ弾性部材24Rを配置するときに、後レッグ弾性部材24Rの伸長度合いを変更することによって、横断部分24R1及び非横断部分24R2の伸縮応力を変更することが可能である。また、横断部分24R1及び非横断部分24R2は、異なる種類の材料によって構成されていてもよい。 For example, when the rear leg elastic member 24R is disposed between the exterior topsheet 21 and the rear exterior backsheet 22R, by changing the extension degree of the rear leg elastic member 24R, the crossing portion 24R1 and the non-crossing portion 24R2 are changed. It is possible to change the stretching stress. Further, the transverse portion 24R1 and the non-crossing portion 24R2 may be made of different types of materials.
 なお、パターン4において、非横断部分24R2の伸縮応力は、横断部分24R1の伸縮応力よりも大きく、中央弾性部材41Cの伸縮応力よりも大きいことが好ましい。 In the pattern 4, the stretching stress of the non-crossing portion 24R2 is preferably larger than the stretching stress of the transverse portion 24R1 and larger than the stretching stress of the central elastic member 41C.
 ここで、糸状弾性部材が同一の弾性部材であれば、糸状弾性部材の本数が多い方が、糸状弾性部材が配置される部分の伸縮応力が大きい。糸状弾性部材が同一の弾性部材であり、糸状弾性部材の本数が同じであれば、糸状弾性部材が太い方が、糸状弾性部材が配置される部分の伸縮応力が大きい。 Here, if the thread-like elastic member is the same elastic member, the larger the number of thread-like elastic members, the greater the expansion / contraction stress of the portion where the thread-like elastic member is arranged. If the thread-like elastic member is the same elastic member and the number of thread-like elastic members is the same, the thicker the thread-like elastic member, the greater the stretching stress at the portion where the thread-like elastic member is disposed.
 ここで、横断部分24R1の伸長率は、例えば、80%未満である。すなわち、横断部分24R1の伸長倍率は、例えば、1.8倍未満である。非横断部分24R2の伸長率は、例えば、50%~300%である。すなわち、非横断部分24R2の伸長倍率は、例えば、1.5倍~4.0倍である。中央弾性部材41Cの伸長率は、例えば、20%~200%である。すなわち、中央弾性部材41Cの伸長倍率は、例えば、1.2倍~3.0倍である。 Here, the elongation rate of the transverse portion 24R1 is, for example, less than 80%. That is, the expansion ratio of the transverse portion 24R1 is, for example, less than 1.8 times. The elongation ratio of the non-crossing portion 24R2 is, for example, 50% to 300%. That is, the extension magnification of the non-crossing portion 24R2 is, for example, 1.5 to 4.0 times. The elongation percentage of the central elastic member 41C is, for example, 20% to 200%. That is, the expansion ratio of the central elastic member 41C is, for example, 1.2 to 3.0 times.
 また、糸状弾性部材が配置される部分の伸縮応力については、以下に示す手順によって測定することができる。なお、糸状弾性部材が配置される部分では、例えば、不織布などの1対の生地によって糸状弾性部材が挟まれていることに留意すべきである。 Further, the stretching stress of the portion where the thread-like elastic member is arranged can be measured by the following procedure. It should be noted that at the portion where the thread-like elastic member is disposed, the thread-like elastic member is sandwiched between, for example, a pair of fabrics such as a nonwoven fabric.
 (1)弛緩状態(非伸長状態)において、糸状弾性部材が配置される部分(測定対象部分)を切り出す。例えば、糸状弾性部材が延びる方向(以下、伸長方向)における測定対象部分の長さは、150mmであり、伸長方向に略直交する方向における測定対象部分の幅は、25mmである。 (1) In a relaxed state (non-stretched state), a portion (measurement target portion) where the thread-like elastic member is disposed is cut out. For example, the length of the measurement target part in the direction in which the thread-like elastic member extends (hereinafter referred to as the extension direction) is 150 mm, and the width of the measurement target part in the direction substantially orthogonal to the extension direction is 25 mm.
 (2)測定対象部分が自然長となるまで、測定対象部分を伸長方向に沿って伸長する。続いて、伸長方向において所定マーキング間隔(自然長)で1対のマーカを測定対象部分に付す。例えば、1対のマーカの所定マーキング間隔(自然長)は、100mmである。 (2) Extend the measurement target portion along the extension direction until the measurement target portion has a natural length. Subsequently, a pair of markers is attached to the measurement target portion at a predetermined marking interval (natural length) in the extending direction. For example, the predetermined marking interval (natural length) of a pair of markers is 100 mm.
 (3) 弛緩状態において、測定対象部分を放置する。例えば、恒温(20~23℃)、かつ、恒湿(60~65%RH)の環境下において、24時間に亘って測定対象部分を放置する。恒温かつ恒湿の環境下で測定対象部分を放置する理由は、応力戻りが安定するまで、一定条件下で放置する必要があるためである。また、次に示す引張り試験においても弾性に影響を与えないように、上記恒温恒湿の同一の環境のもとで行う。 (3) Leave the measurement target part in the relaxed state. For example, the measurement target part is left for 24 hours in a constant temperature (20 to 23 ° C.) and constant humidity (60 to 65% RH) environment. The reason why the measurement target part is left under a constant temperature and humidity environment is that it is necessary to leave under a certain condition until the stress return is stabilized. Also, the following tensile test is performed under the same constant temperature and humidity environment so as not to affect the elasticity.
 (4) 引張試験機は、弛緩状態において、伸長方向において、1対のマーカに揃えて、測定対象部分の両側をチャックする。続いて、引張試験機は、マーカの間隔が所定マーキング間隔(測定)となるまで、測定対象部分を伸長する。所定マーキング間隔(測定)は、所定マーキング間隔(自然長)よりも狭い。例えば、所定マーキング間隔(測定)は、所定マーキング間隔(自然長)の70%である。また、測定対象部分の伸長速度は、100mm/分である。なお、所定マーキング間隔(測定)が所定マーキング間隔(自然長)よりも狭い理由は、糸状弾性部材を挟む不織布などの生地が破損しないようにするためである。また、引張試験機としては、例えば、株式会社島津製作所製オートグラフ型引張試験機(型名:AG-I)を用いることができる。 (4) In the relaxed state, the tensile tester chucks both sides of the part to be measured, aligned with a pair of markers in the extending direction. Subsequently, the tensile tester extends the measurement target portion until the marker interval reaches a predetermined marking interval (measurement). The predetermined marking interval (measurement) is narrower than the predetermined marking interval (natural length). For example, the predetermined marking interval (measurement) is 70% of the predetermined marking interval (natural length). The extension speed of the measurement target portion is 100 mm / min. The reason why the predetermined marking interval (measurement) is narrower than the predetermined marking interval (natural length) is to prevent the cloth such as the nonwoven fabric sandwiching the thread-like elastic member from being damaged. As the tensile tester, for example, an autograph type tensile tester (model name: AG-I) manufactured by Shimadzu Corporation can be used.
 (5)マーカの間隔が所定マーキング間隔(測定)となるまで伸長された状態で、測定対象部分に働く応力(伸縮応力)を測定する。なお、伸縮応力の単位は、例えば、Nである。 (5) Measure the stress (stretching stress) acting on the part to be measured in a state where the marker is extended until the marker interval reaches a predetermined marking interval (measurement). Note that the unit of the stretching stress is N, for example.
 但し、伸縮応力を比較する際には、測定対象部分に含まれる糸状弾性部材の本数が異なる場合があることに留意すべきである。例えば、上述したパターン3では、横断部分24R1から切り出された測定対象部分に含まれる糸状弾性部材の本数は、非横断部分24R2から切り出された測定対象部分に含まれる糸状弾性部材の本数よりも少ない。 However, when comparing the stretching stress, it should be noted that the number of thread-like elastic members included in the measurement target portion may be different. For example, in the above-described pattern 3, the number of thread-like elastic members included in the measurement target portion cut out from the crossing portion 24R1 is smaller than the number of thread-like elastic members included in the measurement target portion cut out from the non-crossing portion 24R2. .
 具体的には、応力を測定したいギャザーをギャザー幅(例えば、4本の弾性部材によって構成されるギャザー)の際で切り出し、切り出したギャザーについて全体応力を測定する。測定した全体応力を切り出したギャザー幅に応じて、10mm(1cm)当たりの応力に換算し、換算した値をギャザーの応力とする。このように換算された伸縮応力を比較する。 Specifically, a gather whose stress is to be measured is cut out at a gather width (for example, a gather constituted by four elastic members), and the overall stress is measured for the cut-out gather. The measured overall stress is converted into a stress per 10 mm (1 cm) according to the gathered width, and the converted value is used as the gather stress. The expansion / contraction stress thus converted is compared.
 例えば、例えば、25mm幅で取り出した中に4本の弾性部材が含まれており、その4本の弾性部材の外外間(4本中の1本目幅方向の外側端部~4本目幅方向の外側端部)の距離が15mmであって、測定値がAであれば、単位幅当たりの応力値X1は、X1=A×10/15(N/cm)となる。弾性部材の間隔(外外間の距離)が、取り出した測定対象部分の中で、部分的に異なっている場合は、測定対象部分における間隔のおおよその平均値を求め、計算に用いる。 For example, for example, four elastic members are included in a 25 mm width taken out, and between the outer and outer portions of the four elastic members (outer end portions in the first width direction to four in the fourth width direction). If the distance of the outer end portion is 15 mm and the measured value is A, the stress value X1 per unit width is X1 = A × 10/15 (N / cm). If the distance between the elastic members (distance between the outside and the outside) is partially different among the extracted measurement object parts, an approximate average value of the distances in the measurement object parts is obtained and used for the calculation.
 また、弾性部材が糸状ではなくシート状の場合であれば、採取幅の中に含まれる弾性部材の幅を求め(Cmm)、測定値をその幅で割り返すことで求めることができる。ここで、測定値がA’であれば、単位幅当たりの応力値X2は、X2=A’÷C×10 (N/cm)となる。測定サンプルを採取する際は、対象となる弾性部材以外の弾性部材が含まれないように考慮する必要がある。 Also, if the elastic member is in the form of a sheet instead of a thread, it can be obtained by obtaining the width of the elastic member included in the sampling width (Cmm) and dividing the measured value by that width. Here, if the measured value is A ′, the stress value X2 per unit width is X2 = A ′ ÷ C × 10 (N / cm). When collecting a measurement sample, it is necessary to consider so that elastic members other than the elastic member used as object are not included.
 実施形態によれば、中央弾性部材41Cは、股下領域120において吸収体に重なっており、かつ、幅方向Wの略中央において長手方向Lに沿って延びるように配置される。すなわち、中央弾性部材41Cによって***域と吸収体との密着性が向上する。従って、尿速が遅いケースであっても、着用物品1の外部に尿が漏れ出すことを抑制することができる。また、伸縮応力線のうち、吸収体を横断する部分(例えば、横断部分24R1)の伸縮応力は、中央弾性部材41Cの伸縮応力よりも小さい。すなわち、吸収体を横断する部分(例えば、中間領域120R)において、伸縮応力が相対的に小さい尿溜まり320が形成される。従って、尿量が多いケースであっても、着用物品1の外部に尿が漏れ出すことを抑制することができる。 According to the embodiment, the central elastic member 41 </ b> C overlaps the absorber in the crotch region 120 and is disposed so as to extend along the longitudinal direction L at the approximate center in the width direction W. That is, the adhesiveness between the excretion area and the absorber is improved by the central elastic member 41C. Therefore, even in a case where the urine speed is slow, urine can be prevented from leaking out of the worn article 1. Moreover, the expansion stress of the part (for example, crossing part 24R1) which crosses an absorber among elastic stress lines is smaller than the elastic stress of 41 C of center elastic members. That is, a urine pool 320 having a relatively small expansion / contraction stress is formed in a portion (for example, the intermediate region 120R) crossing the absorber. Therefore, even in a case where the amount of urine is large, leakage of urine to the outside of the wearing article 1 can be suppressed.
 実施形態によれば、後レッグ弾性部材24R(例えば、非横断部分24R2)の伸縮応力は、中央弾性部材41Cの伸縮応力よりも大きい。従って、尿溜まり320に尿が溜まった場合であっても、後レッグ弾性部材24R(例えば、非横断部分24R2)の引き上げ効果によって、尿の重量に起因する着用物品1のずり落ちを抑制することができる。 According to the embodiment, the stretching stress of the rear leg elastic member 24R (for example, the non-crossing portion 24R2) is larger than the stretching stress of the central elastic member 41C. Therefore, even when urine is collected in the urine pool 320, the pull-up effect of the rear leg elastic member 24R (for example, the non-crossing portion 24R2) suppresses the sliding of the wearing article 1 due to the weight of urine. Can do.
 実施形態によれば、中央弾性部材41Cを構成する複数本の糸状弾性部材の間隔Pが後レッグ弾性部材24Rを構成する複数本の糸状弾性部材の間隔Qよりも小さいため、中央弾性部材41Cによって、***域に対する吸収体の密着性が高い。一方で、間隔Qが間隔Pよりも大きいため、着用者の脚周り部分の肌に対する着用物品1の当たりが弱く、着用物品1が部分的に着用者の脚周り部分の肌に押し当てられないため、着用時の弾性部材による締め付け感をやわらげることができる。 According to the embodiment, since the interval P between the plurality of thread-like elastic members constituting the central elastic member 41C is smaller than the interval Q between the plurality of thread-like elastic members constituting the rear leg elastic member 24R, the center elastic member 41C The adherence of the absorber to the excretion zone is high. On the other hand, since the interval Q is larger than the interval P, the wearing article 1 is weakly hit against the skin around the wearer's leg, and the wearing article 1 is not partially pressed against the skin around the wearer's leg. Therefore, the feeling of tightening by the elastic member at the time of wearing can be eased.
 [変更例1]
 以下において、第1実施形態の変更例1について、図面を参照しながら説明する。以下においては、第1実施形態との相違点について主として説明する。
[Modification 1]
Hereinafter, Modification Example 1 of the first embodiment will be described with reference to the drawings. In the following, differences from the first embodiment will be mainly described.
 具体的には、第1実施形態では、中央弾性部材41Cは、中間領域120Rに達していない。これに対して、変更例1では、中央弾性部材41Cは、中間領域120Rに達している。 Specifically, in the first embodiment, the central elastic member 41C does not reach the intermediate region 120R. On the other hand, in the first modification, the central elastic member 41C reaches the intermediate region 120R.
 (伸縮応力の関係)
 以下において、変更例1に係る伸縮応力の関係について、図面を参照しながら説明する。以下においては、図10~図12を参照しながら、パターン5~パターン7について説明する。なお、図10~図12では、長手方向Lにおける着用物品1の全体が示されている。
(Relationship between stretching stress)
Hereinafter, the relationship between the stretching stresses according to the modification example 1 will be described with reference to the drawings. Hereinafter, the patterns 5 to 7 will be described with reference to FIGS. 10 to 12, the entire wearing article 1 in the longitudinal direction L is shown.
 図10~図12に示すように、パターン5~パターン7の共通構成として、着用物品1は、以下の構成を有する。具体的には、着用物品1は、後胴回り領域110R及び股下領域120を有する。股下領域120は、股下直下領域120M及び中間領域120Rを有する。 As shown in FIGS. 10 to 12, as a common configuration of the patterns 5 to 7, the wearing article 1 has the following configuration. Specifically, the wearing article 1 has a rear waistline region 110 </ b> R and a crotch region 120. The crotch region 120 includes a crotch immediate region 120M and an intermediate region 120R.
 股下直下領域120Mは、着用者が両脚を閉じたときに両脚間の幅が最も狭くなる着用者の股間(例えば、女性の***口の近傍)に当接する領域である。中間領域120Rは、股下直下領域120Mと後胴回り領域110Rとの間に介在する領域である。 The region 120M immediately below the crotch is a region that comes into contact with the wearer's crotch where the width between the legs is the narrowest when the wearer closes both legs (for example, in the vicinity of the female excretion opening). The intermediate region 120R is a region interposed between the inseam region 120M and the rear waistline region 110R.
 上述した中央弾性部材41Cは、股下直下領域120Mにおいて長手方向Lに沿って延びるように配置される。但し、中央弾性部材41Cは、中間領域120Rに達している。 The central elastic member 41C described above is arranged so as to extend along the longitudinal direction L in the region 120M immediately below the crotch. However, the central elastic member 41C reaches the intermediate region 120R.
 具体的には、中央弾性部材41Cは、股下直下部分41C1及び延接部分41C2を有する。股下直下部分41C1は、長手方向Lにおいて着用物品1の略中央部分に設けらる。言い換えると、股下直下部分41C1は、股下直下領域120Mに設けられる。延接部分41C2は、長手方向Lにおいて股下直下部分41C1に連続する部分である。言い換えると、延接部分41C2は、中間領域120Rに設けられる。 Specifically, the central elastic member 41C has a crotch immediate lower part 41C1 and an extended part 41C2. The crotch immediately below portion 41 </ b> C <b> 1 is provided in a substantially central portion of the wearing article 1 in the longitudinal direction L. In other words, the inseam directly below portion 41C1 is provided in the inseam directly below region 120M. The extended contact portion 41C2 is a portion that is continuous with the crotch immediately below portion 41C1 in the longitudinal direction L. In other words, the extended portion 41C2 is provided in the intermediate region 120R.
 後レッグ弾性部材24Rは、伸縮応力線310の一部を構成する。後レッグ弾性部材24Rは、伸縮応力線310上において、吸収体を横断する部分で不連続である。すなわち、伸縮応力線310上において、吸収体を横断する部分には、後レッグ弾性部材24Rが設けられていない。 The rear leg elastic member 24R constitutes a part of the stretching stress line 310. The rear leg elastic member 24 </ b> R is discontinuous at the portion crossing the absorber on the stretching stress line 310. That is, the rear leg elastic member 24 </ b> R is not provided in a portion crossing the absorber on the stretch stress line 310.
 ここで、延接部分41C2の伸縮応力は、パターン5~パターン7に共通して、股下直下部分41C1の伸縮応力よりも小さい。従って、延接部分41C2が設けられる部分(中間領域120R)には、伸縮応力が相対的に小さい尿溜まり320が形成される。 Here, the expansion / contraction stress of the extended contact portion 41C2 is smaller than the expansion / contraction stress of the portion 41C1 directly below the crotch, common to the patterns 5 to 7. Therefore, a urine pool 320 having a relatively small expansion / contraction stress is formed in a portion (intermediate region 120R) where the extended portion 41C2 is provided.
 (パターン5)
 以下において、パターン5について、図10を参照しながら説明する。図10に示すように、中央弾性部材41Cは、股下直下部分41C1及び延接部分41C2を有する。
(Pattern 5)
Hereinafter, the pattern 5 will be described with reference to FIG. As shown in FIG. 10, the central elastic member 41 </ b> C has a crotch immediate lower portion 41 </ b> C <b> 1 and an extended contact portion 41 </ b> C <b> 2.
 パターン5では、延接部分41C2は、断続的に切断さている。例えば、延接部分41C2には、カッターなどによって断続的なミシン目が入っている。これによって、延接部分41C2の伸縮応力は、股下直下部分41C1の伸縮応力よりも小さくなる。 In the pattern 5, the extended part 41C2 is cut intermittently. For example, the extended portion 41C2 has intermittent perforations by a cutter or the like. As a result, the expansion / contraction stress of the extended contact portion 41C2 becomes smaller than the expansion / contraction stress of the inseam directly below portion 41C1.
 なお、パターン5において、後レッグ弾性部材24Rの伸縮応力は、延接部分41C2の伸縮応力よりも大きく、股下直下部分41C1の伸縮応力よりも大きいことが好ましい。 In the pattern 5, the stretching stress of the rear leg elastic member 24R is preferably larger than the stretching stress of the extending part 41C2 and larger than the stretching stress of the part directly under the crotch 41C1.
 (パターン6)
 以下において、パターン6について、図11を参照しながら説明する。図11に示すように、中央弾性部材41Cは、股下直下部分41C1及び延接部分41C2を有する。
(Pattern 6)
Hereinafter, the pattern 6 will be described with reference to FIG. As shown in FIG. 11, the central elastic member 41 </ b> C has a crotch immediately below portion 41 </ b> C <b> 1 and an extended contact portion 41 </ b> C <b> 2.
 パターン6では、中央弾性部材41Cは、複数本の糸状弾性部材によって構成される。延接部分41C2を構成する糸状弾性部材の本数は、股下直下部分41C1を構成する糸状弾性部材の本数よりも少ない。これによって、延接部分41C2の伸縮応力は、股下直下部分41C1の伸縮応力よりも小さくなる。 In the pattern 6, the central elastic member 41C is composed of a plurality of thread-like elastic members. The number of thread-like elastic members that constitute the extended contact portion 41C2 is smaller than the number of thread-like elastic members that constitute the crotch-lower part 41C1. As a result, the expansion / contraction stress of the extended contact portion 41C2 becomes smaller than the expansion / contraction stress of the inseam directly below portion 41C1.
 なお、パターン6において、後レッグ弾性部材24Rの伸縮応力は、延接部分41C2の伸縮応力よりも大きく、股下直下部分41C1の伸縮応力よりも大きいことが好ましい。 In the pattern 6, the stretching stress of the rear leg elastic member 24R is preferably larger than the stretching stress of the extending portion 41C2 and larger than the stretching stress of the portion directly below the crotch 41C1.
 (パターン7)
 以下において、パターン7について、図12を参照しながら説明する。図12に示すように、中央弾性部材41Cは、股下直下部分41C1及び延接部分41C2を有する。
(Pattern 7)
Hereinafter, the pattern 7 will be described with reference to FIG. As shown in FIG. 12, the central elastic member 41C has a crotch immediate lower portion 41C1 and an extended contact portion 41C2.
 パターン7では、延接部分41C2の伸縮応力は、股下直下部分41C1の伸縮応力よりも小さい。 In the pattern 7, the stretching stress of the extended portion 41C2 is smaller than the stretching stress of the portion 41C1 immediately below the crotch.
 例えば、吸収体裏面シート35と中央弾性部材被覆シート42Cとの間に中央弾性部材41Cを配置するときに、中央弾性部材41Cの伸長度合いを変更することによって、股下直下部分41C1及び延接部分41C2の伸縮応力を変更することが可能である。また、股下直下部分41C1及び延接部分41C2は、異なる種類の材料によって構成されていてもよい。 For example, when the central elastic member 41C is disposed between the absorber back sheet 35 and the central elastic member covering sheet 42C, the degree of expansion of the central elastic member 41C is changed to thereby change the inseam directly below portion 41C1 and the extended contact portion 41C2. It is possible to change the stretching stress. Further, the crotch immediately below portion 41C1 and the extended contact portion 41C2 may be made of different types of materials.
 なお、パターン7において、後レッグ弾性部材24Rの伸縮応力は、延接部分41C2の伸縮応力よりも大きく、股下直下部分41C1の伸縮応力よりも大きいことが好ましい。 In the pattern 7, the stretching stress of the rear leg elastic member 24R is preferably larger than the stretching stress of the extending portion 41C2 and larger than the stretching stress of the portion directly below the crotch 41C1.
 変更例1によれば、中央弾性部材41Cの股下直下部分41C1は、長手方向Lにおいて着用物品1の略中央部分に設けられる。すなわち、中央弾性部材41Cの股下直下部分41C1によって***域と吸収体との密着性が向上する。従って、尿速が遅いケースであっても、着用物品1の外部に尿が漏れ出すことを抑制することができる。また、中央弾性部材41Cのうち、延接部分41C2の伸縮応力は、股下直下部分41C1の伸縮応力よりも小さい。すなわち、股下直下部分41C1に連続する延接部分41C2(例えば、中間領域120R)において、伸縮応力が相対的に小さい尿溜まり320が形成される。従って、尿量が多いケースであっても、着用物品1の外部に尿が漏れ出すことを抑制することができる。 According to the first modification, the crotch immediate lower portion 41C1 of the central elastic member 41C is provided in the substantially central portion of the wearing article 1 in the longitudinal direction L. That is, the adhesion between the excretion area and the absorbent body is improved by the portion 41C1 directly below the crotch of the central elastic member 41C. Therefore, even in a case where the urine speed is slow, urine can be prevented from leaking out of the worn article 1. Further, in the central elastic member 41C, the expansion / contraction stress of the extending portion 41C2 is smaller than the expansion / contraction stress of the crotch immediate lower portion 41C1. That is, a urine pool 320 having a relatively small expansion / contraction stress is formed in the extending contact portion 41C2 (for example, the intermediate region 120R) continuous to the crotch immediately below portion 41C1. Therefore, even in a case where the amount of urine is large, leakage of urine to the outside of the wearing article 1 can be suppressed.
 パターン5~7では、吸収体表面シート32の非肌面側に延接部分41C2が重なっていることが好ましい。これによって、吸収体表面シート32の剛性によって、延接部分41C2の伸縮応力が抑制されるため、尿溜まり320が形成されやすい。 In the patterns 5 to 7, it is preferable that the extended portion 41C2 overlaps the non-skin surface side of the absorbent body surface sheet 32. As a result, the stretching stress of the extended contact portion 41C2 is suppressed by the rigidity of the absorbent body surface sheet 32, and thus the urine pool 320 is easily formed.
 また、股下直下部分41C1に連続する延接部分41C2が設けられていると、延接部分41C2に重なる吸収体に尿が吸収されて吸収体が重くなっても、着用物品1が過剰に垂れ下がることを抑制することができる。 In addition, when the extended contact portion 41C2 continuous to the inseam directly below portion 41C1 is provided, the worn article 1 droops excessively even if urine is absorbed by the absorbent body that overlaps the extended contact portion 41C2 and the absorbent body becomes heavy. Can be suppressed.

Drawing 13 is a flow figure showing a part of manufacturing method of wearing article 1 concerning an embodiment. In addition, about the method which is not described in FIG. 13, the existing method can be used.
 図13に示すように、ステップS101において、外装トップシート21を構成するためのシート部材と前外装バックシート22Fを構成するためのシート部材との間に、前ウェスト弾性部材23F及び前レッグ弾性部材24Fを構成するための弾性部材を配置する。また、外装トップシート21を構成するためのシート部材と後外装バックシート22Rを構成するためのシート部材との間に、後ウェスト弾性部材23R及び後レッグ弾性部材24Rを構成するための弾性部材を配置する。 As shown in FIG. 13, in step S101, the front waist elastic member 23F and the front leg elastic member are disposed between the sheet member for configuring the exterior topsheet 21 and the sheet member for configuring the front exterior backsheet 22F. An elastic member for constituting 24F is arranged. Further, an elastic member for constituting the rear waist elastic member 23R and the rear leg elastic member 24R is provided between the sheet member for constituting the exterior topsheet 21 and the sheet member for constituting the rear exterior backsheet 22R. Deploy.
 ステップS102において、外装トップシート21、前外装バックシート22F及び後外装バックシート22Rの形状に合わせて、シート部材間に弾性部材が配置された中間部材をカットする。 In step S102, the intermediate member in which the elastic member is disposed between the sheet members is cut in accordance with the shapes of the exterior topsheet 21, the front exterior backsheet 22F, and the rear exterior backsheet 22R.
 ステップS103において、ステップS102でカットされた中間部材の所定位置に吸収体本体200を配置する。 In step S103, the absorbent body 200 is disposed at a predetermined position of the intermediate member cut in step S102.
 ステップS104において、ステップS103で吸収体本体200が配置された中間部材を折り畳む。 In step S104, the intermediate member on which the absorbent body 200 is arranged in step S103 is folded.
 ステップS105において、ステップS104で折り畳まれた中間部材を接合する。具体的には、前胴回り領域110Fの両側端111Fと対応する部分と後胴回り領域110Rの両側端111Rと対応する部分とを接合する。 In step S105, the intermediate members folded in step S104 are joined. Specifically, a portion corresponding to both side ends 111F of the front waistline region 110F and a portion corresponding to both side ends 111R of the rear waistline region 110R are joined.
 ここで、後レッグ弾性部材24Rの伸縮応力を変更する方法について、図面を参照しながら説明する。すなわち、ステップS101の処理の詳細について説明する。 Here, a method for changing the stretching stress of the rear leg elastic member 24R will be described with reference to the drawings. That is, details of the processing in step S101 will be described.
 第1に、第1方法について、図14を参照しながら説明する。図14に示すように、後レッグ弾性部材24Rを構成するための弾性部材401は、各種ローラによって、伸長率変更装置410のアーム411の先端に設けられたローラに係止される。さらに、弾性部材401は、トラバース装置430によって所定位置に調整された上で、搬送ローラ440に導かれる。一方で、後外装バックシート22Rを構成するためのシート部材402は、各種ローラによって、塗布装置420によって接着剤(例えば、ホットメルト接着剤)を塗布され、搬送ローラ440に導かれる。また、外装トップシート21を構成するためのシート部材403も搬送ローラ440に導かれる。弾性部材401、シート部材402及びシート部材403は、搬送ローラ440と押し付けローラ450との間を通るように導かれ、弾性部材401がシート部材402とシート部材403との間に接着される。 First, the first method will be described with reference to FIG. As shown in FIG. 14, the elastic member 401 for constituting the rear leg elastic member 24 </ b> R is locked to a roller provided at the tip of the arm 411 of the extension rate changing device 410 by various rollers. Further, the elastic member 401 is adjusted to a predetermined position by the traverse device 430 and then guided to the conveying roller 440. On the other hand, the sheet member 402 for constituting the rear exterior backsheet 22R is applied with an adhesive (for example, hot melt adhesive) by the application device 420 by various rollers, and is guided to the conveying roller 440. Further, the sheet member 403 for constituting the exterior top sheet 21 is also guided to the transport roller 440. The elastic member 401, the sheet member 402, and the sheet member 403 are guided so as to pass between the conveying roller 440 and the pressing roller 450, and the elastic member 401 is bonded between the sheet member 402 and the sheet member 403.
 ここで、伸長率変更装置410は、アーム411を回動可能に支持しており、アーム411の回動によって弾性部材401の伸長率を変更する。なお、前ウェスト弾性部材23F、後ウェスト弾性部材23R及び前レッグ弾性部材24Fを構成するための弾性部材401もシート部材402とシート部材403との間に接着される。 Here, the extension rate changing device 410 supports the arm 411 so as to be rotatable, and changes the extension rate of the elastic member 401 by the rotation of the arm 411. An elastic member 401 for constituting the front waist elastic member 23F, the rear waist elastic member 23R, and the front leg elastic member 24F is also bonded between the sheet member 402 and the sheet member 403.
 第2に、第2方法について、図15を参照しながら説明する。なお、図15では、図14と同様の構成について、同様の符号を付している。 Second, the second method will be described with reference to FIG. In FIG. 15, the same components as those in FIG. 14 are denoted by the same reference numerals.
 図15に示すように、弾性部材401及びシート部材402は、第1方法と同様に、各種ローラによって、搬送ローラ440と押し付けローラ450との間を通るように導かれ、弾性部材401がシート部材402に接着される。 As shown in FIG. 15, the elastic member 401 and the sheet member 402 are guided by various rollers so as to pass between the conveying roller 440 and the pressing roller 450 as in the first method, and the elastic member 401 is the sheet member. Bonded to 402.
 ここで、第2方法では、ローラ460或いはローラ470の搬送速度弾性部材401の搬送速度を制御することによって弾性部材401の伸長率が変更される。 Here, in the second method, the elongation rate of the elastic member 401 is changed by controlling the conveying speed of the roller 460 or the conveying speed elastic member 401 of the roller 470.
 なお、中央弾性部材41Cについて、伸縮応力を変更する方法は上記レッグ弾性部材24Rで説明したような装置を使って、トラバース装置を除いて、直線的に配置させていくことができる。中央弾性部材41Cを、吸収体裏面シート35と中央弾性部材被覆シート42Cとの間に配置するには、中央弾性部材41Cを上記方法で伸縮応力を調整した上で、スリットノズル方式による塗工方式により直接HMA接着剤を塗布し、中央弾性部材被覆シートに接着し、吸収体裏面シートに合流させ挟み込み圧着固定することによって、中央弾性部材41Cは、中央弾性部材被覆シート42Cと吸収体裏面シートの間に接着される。このとき、HMAを間欠的に塗布することによって、所定の長さに中央弾性部材がセット、固定され、吸収体本体が所定の長さで切断されたときに、中央弾性部材41Cはスナップバックされ、上記所定の長さまでHMA非塗工部が戻り、所定の長さで中央弾性部材被覆シートと吸収体裏面シートの間に固定される。 In addition, about the center elastic member 41C, the method of changing expansion-contraction stress can be arrange | positioned linearly except for a traverse apparatus using the apparatus which was demonstrated by the said leg elastic member 24R. In order to arrange the central elastic member 41C between the absorber back sheet 35 and the central elastic member covering sheet 42C, after adjusting the expansion and contraction stress by the above method, the coating method by the slit nozzle method is used. By directly applying the HMA adhesive, adhering to the central elastic member covering sheet, joining to the absorber back sheet, sandwiching and fixing, the central elastic member 41C becomes the center elastic member covering sheet 42C and the absorber back sheet Glued in between. At this time, by applying HMA intermittently, the central elastic member is set and fixed to a predetermined length, and when the absorber body is cut at a predetermined length, the central elastic member 41C is snapped back. The HMA non-coated portion returns to the predetermined length and is fixed between the central elastic member covering sheet and the absorber back sheet with the predetermined length.
